| Abstract | We present HbH a new control paradigm in order to overcome nodes failures in multihop wireless ad hoc networks. HbH is an enhancement of the IEEE 802.11 protocol, that enables packet and buffer control at the MAC layer. Previous works have shown that the use of acknowledgments at the transport layer in multihop wireless networks reduces considerably the goodput achieved by connections. Instead of using end-to-end or hop-by-hop acknowledgements, with HbH wireless nodes track neighbors transmission to know if packets are correctly delivered and to detect nodes failures. The innovation in our work is in pushing down such control to the MAC layer which allows taking advantage of the broadcast nature of the wireless medium. HbH attempts to provide a reasonable trade-off between reliability and performance as well as complexity. Our objective is also to study the effectiveness of providing end-to- end reliability by using hop-by-hop flow control. We compare the performance of our protocol in J-Sim simulator with the traditional IEEE 802.11. We show that we can increase the reliability of a UDP flow without adding control overhead thus increasing the goodput as well. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
